samba - May 2004 - Samba PDF printer...

Hello

Using Samba 2.2.8a on a Redhat 7.2 box

I set up a PDF generator relying on Samba and a shell script to create 
the output.

This works fine but I have a further trouble that I am stumped by.  The 
files cannot be viewed from within a Citrix session (the point of the 
entire exercise) unless they are available from this one NT Server 
share.  So if I mount a Windows NT server share under '/mnt/gpsc/pdfs' 
and then redirect the output to that directory, everything looks like it 
works but I get no output.

I can create/edit files, as a variety of users, on this NT share from 
the Linux box so I think that part is fine but I cannot do this from 
Samba.  I would normally expect some sort of complaint in the form of a 
log entry but nothing shows up in the logs (log level = 3).

[PDFFiles]
         path = /mnt/gpsc/pdfs
         invalid users          read only = No
         guest ok = Yes

[Create a PDF]
         comment = Check your 'K:' drive for your .PDF file.  Check in 
the folder named 'PDFFiles'.
         path = /tmp
         guest ok = Yes
         printable = Yes
         print command = /usr/local/bin/printpdf %s %m %U
